Fix or disable Docker build

[mikegerber]

Docker builds are failing, the "Details" link to a 404 error page.

• Fix the Docker build
• Do not use calamari/build make target, we are using the version from PyPI
• Check if this Docker build is useful (not using it personally) (→ Build (and Test) Docker container according to specs #36)
• Fix the build on dockercloud?

Build was mostly fixed in 1fda419

Removed calamari/build (stick to pip) in a2d1d76

Automatic builds are working again at https://hub.docker.com/r/ocrd/calamari

Check if this Docker build is useful (not using it personally)

Me neither but that might change in the future. So unless it's masssive effort to support, let's keep the automatic build as-it-is.

Fix the build on dockercloud?

Your setup fixes fixed the build. It automatically rebuilds master to latest on new commits.

What's the problem? Looks like it's building ok?

I moved the remaining TODO to #36.
